Preface

Large-scale biopolymers that may be obtained from various natural sources are the subject of an increasing amount of research. Significant advancements in this sector show how promising it is to create and apply novel biomaterials for a variety of uses. The most prevalent molecule on earth, cellulose, is one of the earliest and most promising biopolymers. The primary sources of cellulose for all goods made or produced from it are wood and cotton. Furthermore, certain bacterial species that may be cultivated in culture are also responsible for the synthesis of cellulose, as are plankton and unicellular algae found in seas. When compared to other naturally occurring or artificially created nanomaterials, bacterial nanocellulose (BNC) is a singular natural nanomaterial. Numerous bacteria have the ability to generate BNC, which helps them survive in various ecological environments. Beyond its potential applications in biology, BNC has also shown promise in the paper sector, as evidenced by recent research. High inter-fiber hydrogen bonding is ensured by its nanoscale fiber size and plenty of free hydroxyl groups. As a result, BNC has a lot of promise for use as a reinforcing material. It works particularly well with recycled and nonwoody cellulose fiber paper. Modified BNC exhibits significant promise for the creation of specialty and fire-resistant sheets in addition to improving the strength and durability of paper. By creating innovative, value-added products that extend the life of paper, BNC has the potential to completely transform the papermaking sector. To make this technique commercially viable, however, the biotechnological components of BNC must be enhanced in order to reduce manufacturing costs. The production of culture techniques, biosynthesis, special structural features, and uses in papermaking and packaging are all covered in this book to highlight the significance of BNC as a highly biocompatible and promising material that can be obtained from sustainable natural resources.
